Description
Technical field
The utility model relates to notebook computer noise testing device.
Background technology
Along with the raising of people's life and the progress of science and technology, computer is more and more universal in life and work.The pursuit of living to high-quality along with people and the pursuit of facilitation, the positive cumulative year after year of notebook computer, uses more and more extensive.Notebook computer, due to easy to carry, be more and more subject to people and welcome, although it has plurality of advantages, also there are some defects.Such as, computer noise problem.When using desktop computer, host desktop can leave the ear of people apart from distant, therefore, its noise is larger a little may can not bring very large discomfort, but notebook computer is owing to being positioned in face of operator, a little some noise, for the long-time people used, then can cause very large noise pollution, impact healthy.Therefore, before dispatching from the factory after notebook computer is made, must test notebook noise.At present the test of notebook computer noise is adopted under open environment, tested by the fan mouth of hand-held noise tester at notebook.This method of testing is succinctly effective, but external environment condition can cause disturbing effect to test, brings error to test result.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of notebook computer and surveys device of making an uproar, and convenient test, test error is little.
For solving the problems of the technologies described above, device of making an uproar surveyed by a kind of notebook computer of the technical scheme that the utility model provides, it is characterized in that comprising shielded box, described shielded box top is provided with the back up pad with hollow frame, two parallel slide rails are arranged at intervals with in shielded box below described back up pad, across being provided with support slide rail on slide rail described in two, described support slide rail is slidably equipped with microphone apparatus, described microphone apparatus is connected with the public address set outside described shielded box, and the shielded box side plate being positioned at described support slide rail one end is openable side plate.
Slide rail described in two is drawer type slide rail, and described support slide rail is fixedly installed on described drawer type slide rail.
Described microphone apparatus comprises and is slidably installed in microphone plate holder on described support slide rail, and microphone plate holder is fixed with microphone, and described microphone is connected with public address set.
Below described microphone plate holder, be provided with adjustment handle, the described support slide rail one end being positioned at described openable side plate side is provided with handle block.
Described shielded box comprises a upper cover, and described upper cover is made up of fixed cover and movable top lid two parts, and described movable top lid is hinged in described fixed cover, and the both sides of described movable top lid are connected with described shielded box biside plate by air spring.
The back up pad at adjacent both sides of the edge place being positioned at described center framework is respectively arranged with positive stop.
Device of making an uproar surveyed by notebook computer of the present utility model, shields external interference by shielded box, reduces metrical error.By being placed on the movement of the drawer type slide rail below bracing frame, driving and moving across the support slide rail on drawer type slide rail, be then slidably installed in the microphone apparatus position supported on slide rail by adjustment, make it aim at notebook computer fan mouth; Realize moving of microphone all around.Its structure is comparatively simple, can the notebook computer of test different types.
Accompanying drawing explanation
Fig. 1, the utility model structural representation.
Fig. 2, inner structure schematic diagram of the present utility model.
Embodiment
For technique scheme, now lift a preferred embodiment and be specifically described in conjunction with diagram.Referring to Fig. 1 to Fig. 2, notebook computer of the present utility model is surveyed device of making an uproar and is mainly comprised shielded box, bracing frame, slide rail, support slide rail, microphone apparatus and public address set, wherein.
Shielded box 1, its upper cover comprises fixed cover and movable top lid 11 two parts movable top lid 11 is hinged in fixed cover, and two relative lateral surfaces of movable top lid 11 are connected with its shielded box side plate respectively by air spring 12.Movable top lid is provided with handle.After movable top lid is opened, can be supported movable top lid by air spring.Four angles inside shielded box are respectively arranged with support column, are fixed with the back up pad 13 with hollow frame on the support columns.The back up pad of the adjacent amount edge of hollow frame is respectively arranged with limited block 14.When notebook computer is placed on the supporting plate, by limited block, its position is limited.Hollow frame meets notebook computer when placing on the supporting plate, and the bottom with fan of notebook computer is all positioned at hollow frame position.
Supported on both sides post is installed with two parallel slide rails 2 below back up pad, in the present embodiment, this slide rail 2 is drawer type slide rail.Two parallel drawer type slide rails supporting slide rail 3 across being fixed with, supporting slide rail 3 and arranging with in a vertical angle the spending of drawer type slide rail.Support slide rail 3 is provided with slide block, slide block is fixed with microphone apparatus 4.Microphone apparatus 4 comprises the microphone plate holder be fixed on slide block, and microphone is fixed on microphone plate holder.Microphone is connected with the public address set of shielded box outside, and public address set is loudspeaker, and amplified by the small noise signal of loudspeaker by notebook computer, convenient detection, reduces test error.Adjustment handle is fixed with below microphone plate holder.Handle block 6 is connected with in support slide rail one end.Be hinged on base plate near the shielded box side plate 7 of handle block 6 side, when side plate 7 is closed, by padlock side plate 7 be locked at and be positioned on the side plate of its both sides, realize shielded box sealing.Owing to being hollow in the shielded box below back up pad, by handle block, support slide rail being moved along drawer type slide rail, drive microphone apparatus to move left and right in shielded box, microphone can be made to move forward and backward along support slide rail by regulating handle.
The principle of work that device of making an uproar surveyed by notebook computer of the present utility model is: open shielded box upper cover and side plate, is placed on the supporting plate by notebook computer, and the both sides of notebook computer are resisted against on limited block.According to notebook computer fan mouth position, by handle block movable support slide rail to the below of notebook computer fan mouth position, then regulate handle to regulate microphone apparatus to locate to notebook computer fan mouth position by push-and-pull, make microphone just to notebook computer fan mouth.Then close side plate and movable top lid, detect notebook computer noise at public address set place.
Device of making an uproar surveyed by notebook computer of the present utility model, and structure is simple, can realize microphone and all around move, can the notebook computer of test different types, owing to there being shielded box to exist, avoids external environment condition interference, reduction metrical error.Usually, when testing same specification notebook computer, after regulating microphone position, noise measuring can be carried out to same specification notebook computer; Only when after notebook specifications vary, need regulate microphone position.The adjustment number of times decreasing microphone position of high degree, facilitates detection.
